Excessive production of reactive oxygen species (ROS) induced by micro/nanoplastics (MPs/NPs) is highly toxic to microbes. However, the mechanisms underlying ROS generation and metabolic regulation within anaerobic guilds remain poorly understood. In this study, we investigated effects environmentally relevant levels polypropylene (PP)-MPs/NPs on oxidative stress microbial ecology during digestion (AD). Electron paramagnetic resonance spectroscopy revealed that PP-MPs/NPs elevated concentrations persistent free radicals (EPFRs) derived hydroxyl (•OH). EPFRs were identified as primary contributors •OH generation, evidenced a high Spearman correlation coefficient (r = 0.884, p < 0.001) radical-quenching studies. The formation enhanced 86.2–100.9%, resulting in decreased cellular viability methane (by 37.5–50.5%) at 100 mg/g TS PP-MPs/NPs. Genome-centric metagenomic metatranscriptomic analyses suggested reassembly community structures, re-evolution functional traits, remodeling interspecies interactions. Specifically, shift methanogen consortia from hydrogenotrophic Methanofollis sp. acetoclastic Methanothrix soehngenii, primarily because latter's diverse ingestion patterns, electron bifurcation complexes, ROS-scavenging abilities. Downregulation genes associated with antioxidative defense systems (i.e., sodN, katA, osmC) ROS-driven redox signal transduction pathways (c-di-AMP phosphorylation signaling pathways) provided insights into ROS-induced dysregulation. Our findings enhance understanding ecological traits under MPs/NPs stressors, facilitating control toxicity stabilization AD processes.
